No matter what, make good art.
Fake it until you make it.
Enjoy life, especially the success.
You’ll do well if you are pleasant to work with, good at what you do, and submit your work on time. And you’ll likely do fine if you only do two of those.
Make up your own rules. The rules are changing; no one can predict them. So go do amazing things, successes and mistakes, and make your own rules.
